Given numbers are 177, 156, 171, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(177, 156) = 9204
GCD(177, 156) = ( 177 x 156 ) / 9204
= 177 / 156
= 177
Step2:
LCM(3, 171) = 171
GCD(3, 171) = ( 3 x 171 ) / 171
= 3 / 171
= 3
Step3:
LCM(3, 487) = 1461
GCD(3, 487) = ( 3 x 487 ) / 1461
= 3 / 487
= 3
So, Greatest Common Divisor of 177, 156, 171, 487 is 1
